Our proprietary Mini Cooper ECU upgrade offers rock solid performance from RENNtech, the foremost tuning authority on Bosch and Siemens engine control units.

These same units are utilized in Mercedes Benz vehicles, which RENNtech has been tuning since electronic engine management started to show up in vehicles during the mid 1980's, though our proprietary tuning software and approach for the Mini is completely unique and independent from our Mercedes tuning program.

RENNtech tuning software for Mini offers significant gains in performance and throttle response without sacrificing daily driver reliability.

By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the top speed limiter and modifying boost mapping for turbo charged vehicles; RENNtech performance software unleashes your Mini's true potential.
